7. Refer to the Accounting field and define the following credentials for a primary and secondary Radius
Server.
8. Select the Re-authentication checkbox to force a periodic re-authentication with the Radius server.
Periodic repetition of the authentication process provides ongoing security for currently authorized
connections. Define an interval between 30 and 65535 seconds.
9. Refer to the Advanced field to define the authentication protocol used with the Radius Server.
10.Click OK to save the changes made to this screen.
Server Retries Enter a value between 1 and 100 to indicate the number of times the switch
attempts to reach the primary or secondary Radius server before giving up.
Dynamic
Authorization
Authorization amongst the Radius servers is conducted dynamically as they
connect and disconnect periodically.
NOTE: The Radius or NAC server’s Timeout and Retries should be less than what is
defined for an MU’s timeout and retries. If the MU’s time is less than the server’s, a fall
back to the secondary server will not work.
Accounting Server
Address
Enter the IP address of the primary and secondary server acting as the Radius
accounting server.
Accounting Port Enter the TCP/IP port number for the primary and secondary server acting as the
Radius accounting data source. The default port is 1813.
Accounting Shared
Secret
Provide a shared secret (password) for user credential authentication with the
primary or secondary Radius accounting server.
Accounting Timeout Enter a value (between 1 and 300 seconds) to indicate the number of elapsed
seconds causing the switch to time out a request to the primary or secondary
accounting server.
Accounting Retries Enter a value between 1 and 100 to indicate the number of times the switch
attempts to reach the primary or secondary Radius accounting server before giving
up.
Accounting Mode Use the Accounting Mode drop-down menu to define the accounting mode as
either
Start-Stop, Stop Only or Start-Interim-Stop. Define the
Interval (in seconds) used with the selected accounting mode.
PAP PAP - Password Authentication Protocol sends a username and password over a
network to a server that compares the username and password to a table of
authorized users. If the username and password are matched in the table, server
access is authorized.
CHAP CHAP is an encrypted authentication method based on Microsoft's challenge/
response authentication protocol.
DSCP/TOS Optionally mark packets with a DiffServ CodePoint (DSCP) in the header. The DSCP
value is stored in the first 6 bits of the Type of Service (ToS) field that is part of the
standard IP header. The DCSP values are associated with a forwarding treatment
called Per Hop Behaviors (PHB). Service can be provisioned (if necessary) by
assigning a DCSP point code from 1 - 6.
